Question

construct a triangle XYZ in which YZ =4.2cm, angle Y=120° and XY=3.9cm. Draw XP perpendicular to ZY(produced if required) ​

Answer 1

Step-by-step explanation:

(i) Draw a line segment which is sufficiently long using ruler.

(ii) Locate points X and Y on it such that XY=5cm.

(iii) At Y, construct a line segment YW, sufficiently large, such that ∠XYZ=100˚ ; use protractor to measure 100˚

(iv) With Y as centre and radius 5.5 cm, draw the line cutting YW at Z; join XZ.

⇒ Then XYZ is the required
